Copyright 1997-2021 the PHP Documentation Group.

Warning

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

mysqli_get_host_info
PDO::getAttribute(PDO::ATTR_CONNECTION_STATUS)

Description

string|false mysql_get_host_info(resource link_identifier= =NULL);

Describes the type of connection in use for the connection, including the server host name.

Parameters

link_identifier

The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect is assumed. If no such link is found, it will try to create one as if mysql_connect had been called with no arguments. If no connection is found or established, an E_WARNING level error is generated.

Return Values

Returns a string describing the type of MySQL connection in use for the connection or false on failure.

Examples

Example 6.34 mysql_get_host_info example

<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
printf("MySQL host info: %s\n", mysql_get_host_info());
?>

    

The above example will output something similar to:

MySQL host info: Localhost via UNIX socket
